Solution Overview

Problem

Existing wireless communication technologies face challenges in remotely powering and controlling electronic devices, especially when they are sealed in packages, as they require physical access or battery presence for updates and operations.

Innovation Solution

A method and apparatus that enable remote wireless powering and control of electronic devices by detecting received power, providing wake-up instructions, and receiving software update information via a wireless communication connection, allowing operations like software updates and settings without disturbing the device's package integrity, using technologies like Bluetooth, NFC, and RFID for communication and power transfer.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If wireless communication technologies are used for remote powering and control, then device control capability is improved, but physical access requirement cannot be eliminated

Engineering Contradiction:
Improvedevice control capabilityVSAvoidphysical access requirement
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent uses the wireless signal as an intermediary carrier that simultaneously delivers power and control commands. The modulated wireless signal acts as a mediator between the external controller and the sealed device, enabling both powering and control functions to be transmitted through the same communication channel without requiring physical access.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent combines power transmission and control signal transmission into a single unified wireless communication system. By modulating control commands onto the power carrier wave, the system merges two separate functions (powering and control) into one integrated process, eliminating the need for separate physical connections.

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If device is sealed in package for tamper resistance, then security is improved, but remote operation capability deteriorates

Engineering Contradiction:
Improvetamper resistanceVSAvoidremote operation capability
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces mechanical/physical access requirements with electromagnetic field-based wireless communication. By substituting the mechanical opening of packages with electromagnetic signal penetration, the system maintains package integrity for tamper resistance while enabling remote operation through wireless power and control signal transmission.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The wireless communication system performs multiple functions simultaneously: it provides power transmission, control signaling, and status monitoring all through a single communication channel. This multi-functionality allows the sealed package to maintain its protective function while the device remains fully operable remotely.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Reliability

If battery presence is required for updates, then power supply reliability is improved, but update operation complexity increases

Engineering Contradiction:
Improvepower supply reliabilityVSAvoidupdate operation complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts the power supply requirement from the update operation by providing power through wireless transmission during the update process. This separates the power delivery function from the battery component, allowing updates to occur without requiring the battery to be present or removed from the device.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The system performs preliminary power establishment through wireless transmission before initiating the update operation. By pre-providing power through the wireless channel, the system ensures reliable power supply is in place before the complex update process begins, simplifying the overall operation sequence.

Inventive Principle:
Principle #10Preliminary action
